When cast, releases a ball of flame that swirls around whilst priming itself for detonation. Shortly after coming to a stop, the ball causes a massive explosion, inflicting a very large amount of damage to any enemy caught in the large blast radius.
This has a shorter range than the various Fireball spells. However, it is one of the highest damage dealing, single hit pyromancies and has a respectable blast radius that is capable of dealing full damage to sufficiently clustered enemies. Furthermore, Flame Swathe shines against large, slow moving enemies as they will very rarely move out of its blast.
In PvP, this spell is subpar against players as they can easily roll out of the delayed explosion. It does provide a good level of area denial (such as casting it at one's own character's feet) and can prove very useful in certain situations, such as when combined with a parry but it should not be relied on as a primary means of dealing damage.
